Runtime

---

Besides plugin configuration, you also need to initialize it at runtime in your entry file. This is how you can do it:

require('offline-plugin/runtime').install();

ES6/Babel/TypeScript

import * as OfflinePluginRuntime from 'offline-plugin/runtime';
OfflinePluginRuntime.install();

For more details of usage with TypeScript see here

Methods

Runtime has following methods:

install(options: Object)

Starts installation flow for ServiceWorker/AppCache it's safe and must be called each time your page loads (i.e. do not wrap it into any conditions).

applyUpdate()

Used to apply update for existing installation. See install options below.

update()

Performs check for updates of new ServiceWorker/AppCache.

install() Options

Runtime install accepts 1 optional argument, options object. Right now you can use following runtime options:

(right now install() accepts only Events and doesn't have any runtime configuration options)

Events

Note: To use events, they must be explicitly enabled for each tool (ServiceWorker/AppCache) in their options.

onInstalled

Event called exactly once when ServiceWorker or AppCache is installed. Can be useful to display "App is ready for offline usage" message.

onUpdating

Not supported for AppCache

Event called when update is found and browsers started updating process. At this moment, some assets are downloading.

onUpdateReady

Event called when onUpdating phase finished. All required assets are downloaded at this moment and are ready to be updated. Call runtime.applyUpdate() to apply update.

onUpdateFailed

Event called when onUpdating phase failed by some reason. Nothing is downloaded at this moment and current update process in your code should be canceled or ignored.

onUpdated

Event called when update is applied, either by calling runtime.applyUpdate() or some other way by a browser itself.
